4 Claims. 1

This invention relates to supports for beammolds and other forms used inthe construction of reinforced concrete buildings.

The object of the invention is to provide a form support equipped withan adjustable form clamping attachment which may be convenientlyadjusted into proper clamping relation with forms of varying widths andheights and which, when so adjusted, will securely retain the form inits proper position on the support.

Other objects, advantages and characteristic features will be morereadily understood from the following detailed description taken inconnection with the accompanying drawings, in which Fig. 1 is aperspective view of one embodiment of my invention shown in associationwith a beam-mold.

Fig. 2 is a detail perspective view of a clamping bar supporting slideforming part of the assembly shown in Fig. 1.

Referring more particularly to the drawings, 5 designates a verticallyadjustable telescopic form support on which a beam-mold 6 is supportedby my improved form clamping attachment generally indicated at 1.

Support 5 is shown as comprising an upper hollow tubular member 8slidably fitted in a lower tubular member 9 provided with ascrew-threaded lower end H] which is screwed into the threaded socket llof a supporting base l2. The upper member 8 is adapted to be raised andlowered with reference to tubular member 9 to thereby increase ordecrease the overall height of the telescopic support conjointlyprovided by said members. Upper member 8 is supported in adjustedposition by a supporting pin 13 which is passed through selectedopenings M of a series of such openings provided in the walls of thelower tubular member 9. In the present instance, tubular member 9 isshown provided with a multiplicity of vertically and horizontallystaggered openings l4 arranged so that each opening is locateddiametrically opposite a. similar openin provided in an opposite wallportion of the tube.

After major adjustments of the overall height of the support 5 have beenobtained by raising or lowering member 8 to a new position of adjustmentit is possible to effect a finer adjustment of the overall height of thesupport by screwing the tubular member 9 into or out of socket II tothereby effect a slight unitary raising or lowering of the members 8 and9.

My improved form clamping attachment 1 comprises a channel beam I6supporting the bottom wall 6a of the beam-mold 6 and a pair of 2. toclamping bars Hand l1" disposed inv clamping; engagement with thebeam-mold side walls 6b. Beam I6 is arranged with its web portion l8extending vertically, its lower flange l9 resting on a flanged collar 20secured to the upper end of tubular member 8, and its upper flange 2| insupporting contact with the bottom wallvta of beammold 6. A centeringpost 22 extends downwardly from the central portion of beam flange l9and is fitted in the upper ends of member 8.

Each clamping bar I! and I1 is slidably fitted in upper and lower slots32 and 33 provided in the top and bottom portions of a hollowrectangular slide 34 which is slidably mounted on beam It for movementlongitudinally of said beam. The upper portion of each slide 34 is cutaway as indicated at 35 to permit the inner edges of the clamping bars Hto be butted against the side walls 6b of beam-mold '5 by inwardmovement of said slides.

The slides 34 are moved inwardly to dispose the clamping bars I1 and ITin clamping engagement with the sides of the beam-mold by means ofadjusting nuts 40 which are screwed onto screw-threaded portions 4| ofthe beam flanges l9 and 2|.

Each of the clamping bars I! and I1 is provided with a series ofvertically spaced inclined openings 29 through which one or more nails3| may be driven into the adjacent side walls 6b of the beam-mold, asclearly shown in the drawings. This nailing of the clamping bars to thebeammold enables them to be held in adjusted position prior to applyingthe final clamping pressure through the agency of slides 34 andadjusting nuts 40.

Having thus described the nature of my invention it will be understoodthat various modifications may be resorted to within the scope andspirit of the invention as defined by the appended claims.

I claim:

1. A form-support of the character described including a channel beamarranged with its Web extending vertically and its channel formingflanges extendin horizontally so that the upper flange serves as asupporting seat for the form, slide members comprising top, side andbottom walls slidably mounted on said beam and provided with slots inthe top and bottom walls; a

pair of vertically disposed clamping bars slidably fitted in said slotsfor vertical and horizontal adjustment, said bars being adapted forclamping engagement with the side walls of the form supported on saidbeam and means for adjusting said slide members comprising travellingadjusting nuts in screw threaded engagement with said beam.

2. A form-support of the character described comprising a beam, slidesmounted on said beam for movement longitudinally thereof, form clampingmembers carried by said slides and slide adjusting nuts in screwthreaded engagement withsaid beams H 1 t v 3. A term-support of thecharacterv described comprising a beam adapted to supporta form thereon,clamping members slidably mounted on said beam and adapted to beadjusted lengthwise of the beam into clamping engagements with the osides of the form mounted von said beam and means for adjusting saidclamping members comprising travelling adjusting nuts in screw threadedengagement with said beam.

4. A form-support of the character described including a horizontal beamextending across and supporting a bottom wall of the form, slide mem- 4bers comprising top, side and bottom walls slidably mounted on said beamand provided with slots in the top and bottom walls, a pair ofvertically disposed clampin bars slidably fitted in said slots andadapted for clamping engagement with the side walls of the formsupported on said beam and means for adjusting said slide memberscomprising travelling adjusting nuts in screw threaded engagement withsaid beam.
